The invention discloses a connection structure for an inlet of a high-temperature gas cooled reactor main helium fan. The overall structure consists of a main helium fan inlet sealing structure and a gas feeding header which are connected through a flange, wherein a main body of the main helium fan inlet sealing structure consists of an upper baffle plate, a middle baffle plate and a lower baffle plate which are connected through bolts; grooves are respectively formed in the joint of the upper baffle plate and the middle baffle plate as well as the joint of the middle baffle plate and the lower baffle plate and are respectively used for arranging an assembly model of upper sealing rings and a spring ring and an assembly model of lower sealing rings and a spring ring; sealing of an inlet of the main helium fan is realized under the action of stretching of the two assembly models, and the mounting and the dismounting of the main helium fan are facilitated; a ribbed plate on the gas feeding header is fixed on the inner wall of a steam generator shell, so that centering of the connection structure is realized, and the main helium fan and a steam generator can still work normally under severe working conditions such as earthquake, thermal expansion, cold contraction and the like; therefore, the design requirement of a high-temperature gas cooled reactor is met.
Description
technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactor engineering, in particular to an inlet connection structure of a main helium fan of a high-temperature gas-cooled reactor. Background technique [0002] The high-temperature gas-cooled reactor is a high-temperature reactor with graphite as the moderator and helium as the coolant. It is an advanced nuclear reactor with inherent safety, high power generation efficiency, and extremely versatile uses. In January 2006, "Large advanced pressurized water reactor and high temperature gas-cooled reactor nuclear power plant" in the "National Medium and Long-term Science and Technology Development Plan (2006-2020)" officially released by the State Council was included in the national major special project. With the support of this special project, a demonstration project of a high-temperature gas-cooled reactor nuclear power plant with an electric power of 200,000 kilowatts is cur...
